RUDOLF METZ, OF OBERURSEL IN TAUNUS, GERMANY.

ALARM-CLOCK.

T 0 all whom it may concerm i Be it known that I, RUDoLF Man, a subject of the German Emperor, and resident of Oberursel in Taunus, Germany, have in vented an Improved Alarm-Clock, of which the following is a specification.

The present invention is an improved alarm clock, which will prove very useful to people who are hard of hearing, as also to deaf people.

The nature of the invention consists in that an ordinary alarm clock is provided with a sounding device instead of a bell. The alarm clock is attached to the bedstead in such a manner that at a certain time, at which the clock was previously set to go off, the said sounding device is released, just as the hammer is released in the case of a usual alarm clock, and knocks against the bedstead, whereby shocks are experienced by the person lying in bed, which cause him to wake up. 1

The clock and sounding device are so connected to one another, that the whole apparatus can easily be attached to any bed, and can conveniently be carried in a bag when a person is traveling.

The following is a full description of the invention, with reference to the annexed drawing, in which Figure 1 is a longitudinal section through the clock, and Fig. 2 is a back view, the back cover being omitted.

Now referring to the drawing, a is a casing, in the upper part of which is fitted an ordinary alarm clock I), behind a transparent disk 0. The alarm clock I; is put in the casing a by folding down the lid 65 provided at the back of the casing a. This lid (1 is also to be folded down when it is necessary to wind up the clockwork. e is a handle by the aid of which, the alarm works can be wound up. W hen at a certain time, the alarm is disen gaged and the respective work is set in motion, this handle 6 will also revolve, whereby it will come in contact with a rod 9, which. is journaled at Through the power of the running off spring of the alarm works, this rod 9 is pushed to the left with reference to Fig. 2 of the accompanying drawing, and is engaged by a yielding projection it. While the one end of the rod 9 is moved towards the projection h, and engaged there, the other end of said rod releases a fly-wheel i of the sounding device 19 located in the. lower part of the casing a. Through the release of the Specification of Letters Patent.

said fly wheel, the said sounding device is set in operation; it consists essentially of a double armed lever is with ball shaped ends. This double armed lever 7c is set in circular motion, whereby the ball shaped ends alternately operate the hammer Z, which produces sounds (knocks) on the back wall of the casing a. These knocks are transferred to that part of the bedstead at which the clock is fastened, and the thus created shocks are eX- perienced by the person lying in bed. The whole apparatus is attached to the bedstead by a clip m.

The sounding device can be wound up by means of the handle n, the rod 9 however, must be put back into its original position, so that the lower end engages the fly wheel 1), otherwise the said sounding device would run off again immediately it is wound up.

Having fully described my invention, what I claim and desire to secure by Letters Patent is 1. An alarm device, especially adapted for people who are hard of hearing, or deaf, comprising in combination, a casing, an alarm clock, located in said casing, a sounding device connected with said alarm clock, a ham mer operated by said sounding device and a clip,'substantially as described and shown.

2. An alarm device especially adapted for people who are hard of hearing, or deaf, com prising in combination, a casing, an alarm clock, located in said casing, a sounding device connected with said alarm clock, a rod, engaging said sounding device, and a handle, disengaging the sounding device by means of said rod, substantially as described and shown.

3. An alarm device especially adapted for people who are hard of hearing, or deaf, comprising in combination, a casing, an alarm clock, located in said casing, a sounding device connected with the said alarm clock, a hammer, operated by the said sounding device, said hammer designed to produce shocks on the bedstead and a clip, provided on the exterior of the casing for attaching the latter on the bedstead, substantially as described and shown.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
